There is no word on the change-log of the new OS update, but it is believed that this new 5.0.1 Lollipop is a software patch to fix some bugs, which were found in some Nexus devices running 5.0 Lollipop.

Soon after the official roll-out of Android 5.0 in mid-November, some Nexus 5 (and Nexus 7 as well) owners had claimed that they were having trouble tethering to Wi-Fi modems, despite entering the authorised password. The Nexus devices are said to show "Connecting", which becomes "Saved", but never connects.

Even Google's project member had acknowledged the issue under the label - 'defect-18035251' and assured to escalate the issue to the developers' team.

Some of them even complained about the bugs in app switcher, which made random apps to pop-up even after exiting it. Second bug in the SMS apps, made message sending disabled in select Nexus 6, 5, 4 and some select Moto X (2014) devices, reported NDTV Gadgets.

Now with the release of new 5.0.1 update, people believe it might fix all the above bugs.
